February 11th, 2022: What did you learn this week?

This week, I learned why Safari, a browser that I had celebrated for early adoption of parent selectors and CSS level 4 colors, is said to be "the new Internet Explorer" and that it's actually worse, because Microsoft at least always let the users install real alternative browsers.

On an iPhone 6 Plus there is no way to get a rendering engine more up to date than iOS 12.5.5 with Safari 12 (AppleWebKit/604) and so I have to use arcane browser hacks and prefixed vendor properties to make a modern website work on a device, that is still working well, despite its outdated browser and despite Apple's planned obsolesence policy.

What a waste of time!

The code below shows just some of the hacks needed to adjust a website using

• apect-ratio
• height: 100vh
• clip-path
• flex-basis
• flex gap

.home__logo:after {
  -webkit-clip-path: inset(0px -15px -15px -15px); 
  clip-path: inset(0px -15px -15px -15px);
}

/* work around mobile safari 100vh height "features" */
@supports (-webkit-touch-callout: none) {
  @media (max-width: 992px) {
    body.is-burgermenu-open {
      height: -webkit-fill-available;
      max-height: -webkit-fill-available;

Sorry for the rant. I'd rather have spent my time for something more productive this week as well!

Besides, I also learned that Gnome Web has a rendering engine similar to AppleWebkit and might be a good way to test macOS Safari experience on a Linux computer.

I also learnend that Opera mini is still quite popular in Africa and that it still works fine on a modern Android phone and has way less rendering problems than the old iOS Safari.

This week I created my own NFT minting website. The project I built came from the knowledge I got from a udemy course + youtube tutorial.

I am new to Web development so I had to learn myself React and Nextjs (which I am learning till now). I badly want to learn web development because I want to join the web3 craze but I came from a mobile app environment.

I also learned more about Solidity in Crypto Zombies they teach you the basics and fundamentals of coding in Solidity etc.

I learned:

• how to to marshall/unmarshall a JSON in two different ways without duplicating classes, only using Jackson's annotations (gonna write something on my blog about that).
• how to use two different datasources in a single quarkus project

I learned a bunch about GitHub automations from the series by @blackgirlbytes so far. Really looking forward to more.

I learned to work with Nginx on Docker and config fastCGI for php-fpm :) Docker and Nginx official websites was good reference + @techworld_with_nana 's Youtube channel.

• Played around with using Base instead of ReactBootstrap which I typically use and found Base a bit more lightweight and just as easy to use.
• I've been using React 18RC and found it to be quite stable.
• Finally figured out how to configure Nginx so that I could host two separate React apps off the same domain with the main app at mydomain.com and the other app at mydomain.com/secondapp

I have been using swagger for quite awhile, using fastapi, or connecting the swagger UI to other api's. Although, I have never actually used swagger to generate neither the server or the client code.

I always heard about it, but never took the time to try it or even really consider it.
I work with the CEO and apparently he is well aware about using this and has a solid plan in place for how to quickly spin up the API's in this way.

So that is what I learned, instead of writing APIs from scratch, generate the code, and if anything, build a solution that quickly integrates the models.

Brushed up HTML, CSS and JavaScript and built a small game use these. Check it out here. Would be great if you could give some feedbacks.
Learning by doing projects is so awesome!! ❤️

• Started this playlist about Virtual Memory that I will write notes for here
• Reading a white paper on Disruptor, a high performance bounded queue for concurrent exchanges and writing about it here.
• Started reading Company of One - Paul Jarvis.
• Started exploring gc.cpp by doing a code analysis via a jupyter notebook that can be found here.
• Understood how the Counter abstraction works in python.
• Working on diffing two ETW traces and analyzing scores based on the diffs in terms of garbage collection.
• Started re-reading Sharon Lebell's Art of Living, an amazing take on Epictetus' work.

Hey Nick,
I started my own 100 Days of Data Science last week. And I realized that coming up with good ideas is tough. ;^)

Do you recommend placing something on Dev.to every day (even when it is small, like just reading...) or when I come up with a finished product, like an article?

P.S. I plan to write/add notes on the blog daily. ;))
